* Patches by Jon Diekema, 15 Sep 2003:

  - add description for missing CFG_CMD_* entries in the README file
  - sacsng tweaks:
   include/configs/sacsng.h:
       + Support extra bootp options like: 2nd DNS and send hostname
       + Enabling ping and irq command
       + Adding defines for a bunch of misc configrabled options
         (patches for these options will be coming)
       + Adding watchdog support, but it isn't enabled yet.

   board/sacsng/sacsng.c:

       + Suppressing unneeded output when the quiet environment
	 is non-zero.
       + show_boot_progress() now accepts any negative number as a
	 failure code.
       + show_boot_progress() flashes the error code 5 times, and
         then resets the board to retry the boot from the top

* Patch by Gleb Natapov, 14 Sep 2003:
  enable watchdog support for all MPC824x boards that have a watchdog
